Research Summary

I am interested in analyzing the functional dynamics of biomolecular complexes, molecular modeling and simulation approaches. The computational models, I employ include elastic network models (ANM/GNM), Molecular Dynamics (MD) simulations, and Quantum chemical (QM) calculations. The aim is to analyze the 3-D structure of the protein, and its interactions with ligands and/or environment, as a function of space and time. The environment is always water molecules, and may include lipid bilayer, if the biomolecule happens to be a membrane protein. While the amplitudes of motions accessed by biomolecules range from Angstrom to nanometers, the timescales range from picoseconds to micro or even milliseconds. Considering the wide spatio-temporal ranges, it is not practical, to analyze structural dynamics using any single computational model. A judicious approach would be to apply a combination of multi-level computational models. I thus endeavor to help interpret experiments at an atomic level detail and suggest novel experiments, essentially supplementing existing knowledge.
